UNITED STATES Cross Reference PATENT OFFICE BENJAMIN F. BURKE, OF ALTOONA, KANSAS, ASSIGNOR OF ONE-HALF TO FRANK P. MOORE, OE SAME PLACE.

SOAP.

SPECIFICATION forming part of Letters Patent No. 390,647, dated October 9, 1888. Application filed January 13,1888. Serial No. 260.634. (Specimens) To aZZ whom it may concern:

Be it known that 1, BENJAMIN F. BURKE, a citizen of the United States, residing at Altoona, in the county of \Vilson and State of Kansas, have invented certain new and useful Soap Compounds; and I do declare the following to be a full, clear, and exact description of the inventiomsuch as willenable others skilled in the art to which it appertains to make and use the same.

My present invention is more especially designed as an improvement upon the soap compound patented to me on February 9, 1875, by Letters Patent No. 159,6i0; and my object is, first, to provide a soap compound which will obviate the practice of coloring a separate body of water for bluing the fabrics, and thus dispense with a separate bluing compound toimpart the desirable appearance or color to the fabrics; and, secondly, to make the soap lather more freely, and thus produce a greater quantity of soapsuds.

To the ingredients named in my former patent as constituting my soap compoundnamely, sodaash, nnslaked lime, bromide of potassium, muriate of ammonia, water, saltpeter, linseed-oil, and boraXI add a number of raw eggs, a small proportion of glycerine, and a small quantity of concentrated bluing, the latter being of the character known to the trade as Chinese bluing.

The ingredients named above as forming the soap compound of my prior patent serve as a vehicle for the bluing, glycerine, ande gs, and the proportions that I prefer to use in my improved soap is one dozen (12) raw eggs, two (2) ounces of glycerine, and one (1) ounce of the concentrated bluing to every fifty (50) pounds of the vehicle. The vehicle is first properly compounded and prepared in the manner set forth in my prior patent and the raw eggs, glycerine, and bluing added thereto in the proportions above specified, and the whole is then very thoroughly mixed together by agitation in a suitable vessel.

I have found by practical experience thata soap made as herein set forth in the proportions stated lather-s very freely, which is very desirable in washing fabrics, and at the same time it imparts to the water the proper shade or degree of color to give the white and colored linen or other fabrics the desired appearance which is sought to be obtained in ordinary practice by immersing them in aseparate body of colored water after they have been properly cleansed in hot water of the dirt, 8:0.

The soap compound, as herein described, with the raw eggs as an ingredient, should be used within a limited time after its preparation, as the eggs are liable to decay, owing to the lack of a preserving substance in the soap; but it is obvious that a suitable substance of this nature can be added without departing from the spirit ofmy invention.

Having thus described my invention, what I claim is- The herein-described composition of matter to be used as soap, consisting of raw eggs, glycerine, bluing, and a vehicle suitably incorporated therewith, said vehicle being composed ofsoda-ash, lime, bromide of potassium, muriate of ammonia, water, salt-peter, linseedoil, and borax, as described.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN F. BURKE.
